Suddenly stars are dashes with good guiding
Hi Chris, Yes, any slop in the guide assembly, e.g. mounting, camera, focuser, etc., can lead to differential flexure and it can be a real pain to isolate and fix. You mentioned that it appears in the

It sounds like differential flexure to me. Have you check that the guide scope hasn’t worked loose from the main OTA, it won’t need much and you probably won’t even see it. Guide performance may well

Hi Ray, I don't own APCC, I just use the V2 driver. To be more accurate in my description of the problem, it is true that the V2 driver continues to allow me to park with CW up, BUT since August last
